What to pair it with

Our reading of HappyModel’s numbers, so your build matches what the motor was tested with.

Bench data

Redrawn from HappyModel’s test reports. Thrust is static pull on a bench, more than you get in flight. Power is volts × amps; efficiency is thrust divided by power.

Inside the motor

A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:

• Shaft. 1 mm, held in the motor by two E-clips (HappyModel's "double E-clip design"). (HappyModel product page)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 19000KV version reaches about these speeds; a prop loads the motor and brings it down, typically to around 70–75% of these figures at full throttle.

A 12-pole rotor has 6 pole pairs, so every turn of the shaft is 6 electrical cycles, and a six-step ESC switches the phases 36 times per turn.

About the 3D model

A generic outrunner drawn from HappyModel’s published sizes: the 8 × 2 mm stator, 10.5 mm bell, 7.7 mm height, 1 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 magnets. Anything HappyModel doesn’t publish is typical for a motor this size, and the bell’s spoked top, the base and the inside are a generic design, not this motor’s. The colours are read off the maker’s product photos. There are no logos or markings: it is our drawing, not the maker’s.
